  5. In children ADHD is 3-5 times more comon in boys than girls. In adults it is more closer to even,incresing in women and decreasing in men. The prevalence of ADHD in adults declines with age. Partly due to age related the client in the symptoms, tough some patients with ADHD in childhood meet fewer criteria as adults but have persistent symptoms - ADHD in partial remission under DSM 5. Over - activity in adulthood declines more than attention deficit. There is more anxiety, attention deficit, presents more as inability to fulfill the tasks. Problems with employment, finances, interpersonal relationships including workplace, partnerships, divorces and specially as comorbidity of psychiatric disorders (depression, anxiety, substance abuse, including smoking).

  10. Why Should Adult Mental Health Services be Interested in ADHD? • ADHD is a common behavioural disorder associated with significant adult psychopathology, social and academic impairments and the risk for negative long–term outcomes1,2 • ADHD symptoms persist into adult life and cause significant clinical impairments1 • The main clinical issue is recognition of the disorder in adults and quantifying the load on adult psychopathology1 • ADHD is a treatable condition1 Asherson et al. Br J Psychiatry 2007;190:4–5. Antshel et al. BMC Med 2011;9:72.

  11. Treatment outcome Shaw et al. BMC Medicine 2012, 10:99, available at: http//www.biomedcentral.com/1741-7015/10/99

  12. Key Principles • ADHD in adults is no more difficult to diagnose and treat than other common mental health disorders1 • ADHD in adults is a symptomatic disorder (not just about behaviour)1,2 • ADHD in adults is often misdiagnosed for other common adult mental health disorders1,2 • ADHD in adults is in most cases treatable1 Asherson. 1st European Network Adult ADHD Conference. London, 2011. Kooij et al. BMC Psychiatry 2010;10:67.

  13. Assesment • Psychiatric History • Somatic histroy • Screening for most common comorbid disorders • Screening for special and general learning difficulties • Family history • Substance abuse • Forensic history • Asherson. 1st European Network Adult ADHD Conference. London, 2011.

  14. Symptoms of ADHD • Anxiety:1 • Ceaseless thoughts, avoidance behaviour • Depression:1 • Unstable mood, impatience, irritability, initial insomnia, low self-esteem • Personality disorder:1 • Antisocial, borderline, emotionally unstable, poor social interactions, impulsive, adulthood instability trait-like quality • Hypomania, bipolar ll disorder, cyclothymia:2 • Differentiated by grandiosity, clear focus of thoughts, episodic, reduced need for sleep, psychosis Asherson. 1st European Network Adult ADHD Conference. London, 2011. Babcock and Ornstein. Postgraduate Medicine. 2009;121(3):73-82.

  15. Overlapping Neurodevelopmental Disorders • Dyslexia (overlapping genetic risk factors)1 • Specific and general learning difficulties (overlapping genetic risk factors, inattention)1 • Pervasive developmental disorder1 • Dyspraxia1 • Tic disorders/Tourette's disorder1 • Speech problems2 • Autism spectrum disorder1 Kooij et al. BMC Psychiatry 2010;10:67 Tannock et al J Abnl Child Psychol, 2000; 28(3):237–252

  16. ADHD in population with substance abuse disorders and and incarterated population is about 25% - significantly higher than in general population. Philipsen A, Heslinger B, tebartz van Elst. Attention Deficit Hyperactivity Disorder in Adulthood; Diagnosis, Etiology and Therapy. Dtsch Arztebl Int 2008; 105(17): 311-7

  17. Medication for ADHD and criminality: Observational Swedish data base analysis • Rate of Crime Over 4 Years in Swedish ADHD Subjects Aged >15 years (N=25,656) 2. Hazard Ratio for Conviction for Any Crime During ADHD Medication (2006–2009) vs. Non-Medication Periods Crimes occurred less often during medication periods (men 32% reduction, women 41% reduction); however, the observational nature of the data cannot confirm a causal relationship with ADHD medication and other factors co-occuring with medication may play a role Lichtenstein et al. N Engl J Med. 2012;367:2006-14.

  18. High comorbidity of mental health disorders (80%): depression (40-60%), anxiety (20-60%) substance abuse disorders (50-60%). Philipsen A, Heslinger B, tebartz van Elst. Attention Deficit Hyperactivity Disorder in Adulthood; Diagnosis, Etiology and Therapy. Dtsch Arztebl Int 2008; 105(17): 311-7

  19. DD: Depression specially with cognitive disfunction but no continuity of symptoms. Borderline personality disorder – high overlaping the symptoms: Impulsivity and emotional instability Anxiety offten followed by autoagressive/self-harming behaviour, suicidal ideation or PTSD.

  24. Conclusions ADHD is a neurobiological condition characterised by persistent patterns of inattention and/or hyperactivity, impulsiveness, and impairment in executive functioning ADHD symptoms persist into adult life and cause significant clinical, social, economic, psychological, and functional impairment ADHD in adults is often associated with a number of comorbidities Diagnosis of ADHD in adults is a multifaceted process Clinicians should carefully consider comorbidities and medical rule-outs ADHD in adults is a treatable condition

  27. Substance abuse disorders (SUD) are the most common co-morbidity disorder. Nicotine dependence in Germany is 27 %, about 40 % in the USA (1). Second most common disorder is the harmful use of alcohol. In general, patients with ADHD are twice as much at risk of development of drug dependence (2). Co-morbidity of drug dependence is between 45 and 70 % (22-24) and one third of those addicted to alcohol has ADHD. (3,4).15-25 % of adults with SUD fulfill criteria for ADHD.The most common illicit drug is cannabis – 21 %. Cocaine - 11-35 % (5,6). SUD with ADHD patients start earlier, course of the disease is more serious and the prognosis is worse. • Philipsen A, Heslinger B, tebartz van Elst.

  30. Brain Networks Implicated in ADHD • Liston et al. Biol Psychiatry 2011;69:1168–77.

  31. ADHD and Substance Misuse • Reason for the relationship: • High stimulus seeking behaviour: • Inherent component of ADHD (e.g. novelty seeking) • Shared genetic risk • Impaired social/academic/work function: • Secondary consequence of psychosocial impairments • Relief from symptoms: • Self-treatment of symptoms (e.g. cannabis, alcohol, cocaine) Arias et al. Addictive Behaviors 2008;33(9):1199–207. Asherson. 1st European Network Adult ADHD Conference. London, 2011.

  32. 75 % patients with ADHD in childhood have ADHD in adolescence and 50 % in adulthood (1). 66 % children with ADHD have in adulthood at least clnical significant symptom of mental health disorders (2). 25-50 % adolescents with SUD have ADHD. 40-50% those smoking marihuana have ADHD. Adults with ADHD and SUD have more serious symptoms of those disordes and have started using PAS when they were younger (3). • Timoty E, Wilens M.D, R.Morrison N.

  33. Understanding reasons for using PAS is important for treating these patients. Wilson JJ, Levin FR. Attention deficit hyperactivity disorder (ADHD) and substance use disorders. Curr Psychiatry Rep. 2001 December; 3(6): 497-506.

  34. Children with ADHD and comorbid conduct or bipolar disorder have the worst prognosis for SUD (1). Those without these disorders have a moderate risk (2). There is not much research about the role of ADHD and comorbid SUD in women (3). • Brook DW, Brook JS, Zhang C, Koppel J. Association between attention-deficit/hyoeractivity disorder in adolescence and substance use disorder in adulthood. Arch Pediatr Adolesc Med. 2010 Oct; 164(10): 930-4. • Wilens TE. Attention-deficit/hyperactivity disorder and the substance use disorders: the nature of the relationship, subtypes at risk, and treatment issues. Psychiatr Clin North Am. 2004 Jun; 27(2): 283-301. • Lynskey MT, Hall W. Attention deficit hyperactivity disorder and substance use disorder: Is there a causal link? Addiction. 2001 Jun; 96(6): 815-22.

  35. In many patients with SUD ADHD was not recognized or diagnosed. In the group of patients with SUD 54 % had symptoms of ADHD in childhood and it was related to the earlier use of alcohol and other PAS (1).Because ADHD symptoms express earlier as SUD there is a small possibility that the SUD cause ADHD (2).ADHD is a significant risk factor for starting smoking before 15 years and when associated behavioral disorders or mood disorders are particularly risky. Early exposure to nicotine may make the brain more susceptible to subsequent behavioral and emotional disorders and PAS abuse. Hypothesis of selfmedication is of course linked to the fact that ADHD often associated with a loss of motivation, failure as are important factors for the abuse of drugs (2). • Ohlmeier et.al. Alcohol and drug dependence in adults with attention-deficit/hyperactivity disorder: Data from Germany. Eur J Psychiat 2011. Vol 25. N3: 150-163. • Timoty E, Wilens M.D, R.Morrison N. The Intersection of Attention-deficit/Hyperactivity Disorder and Substance Abuse. Curr Opin Psychiatry. 2011 July; 24(4): 208-285

  36. As ADHD is recognizedaheadof PAS abuse it canbesuccessfullytreatedand so thepossibilityofthedevelopmentof SUD andalso ADHD in adulthoodmaybereduced (1). Personswhoabusedrugs are more oftenhospitalizedandhaveworseoutcomes in ADHD in thispopulation (2). Wilenset.alhavedemonstratedsignificantreduction in ADHD symptoms in adultswithalcoholdependencebut no effect on alcoholconsumption (3). 1. Wilson JJ, Levin FR. Attention deficit hyperactivity disorder (ADHD) and substance use disorders. Curr Psychiatry Rep. 2001 December; 3(6): 497-506. 2. Thurstone C et.al.

  37. Atomoxetine in adult patients with ADHD and co-morbid alcohol abuse treated for 12 weeks: LYBY ADHD Investigator Symptom Rating Scale (AISRS) Randomised (n=147) 40.6 40.1 19.0 18.7 21.7 21.4 0 -2 Placebo (n=75) -4 Atomoxetine (n=72) -6 -8 p=0.013 p=0.009 Changes from Baseline -10 -12 -14 Effect Size: 0.48 -16 p=0.007 -18 Hyperactive/ Impulsive Subscale Inattentive Subscale Total Score Wilens et al. Drug Alcohol Depend 2008;96:145-54.

  38. Atomoxetine efficacy in adult ADHD and co-morbid alcohol use disorders: alcohol use This post-hoc analysis demonstrated robust effects of atomoxetine for reducing ADHD symptoms in adult ADHD patients with comorbid alcohol-use disorder and suggests a positive effect on reducing cumulative heavy drinking events over time 35 30 Atomoxetine (N=72) Placebo (N=75) 25 20 15 10 Event ratio=0.737 5 0 0 20 40 60 80 100 Recurrent Heavy Drinking • No worsening of alcohol abuse in patients treated with atomoxetine Randomised (n=147) Cumulative Heavy Drinking Days p=0.0230 Follow-up Time (Days) Wilens et al. Drug Alcohol Depend 2008;96:145-54.

  39. Because of high incidence of ADHD in SUD population we should always have in mind the possibility of ADHD. Correlates with worse quality of life(1). All patients with SUD should be screened for ADHD as soon as their PAS use is stabilisied (2). 1. Fatseas M, Debrabant R, Auriacombe M. The diagnostic accuracy of attention-deficit/hyperactivity disorder in adults with substance use disorders. Curr Opin Psychiatry. 2012 May; 25(3): 219-25. 2.

Ned Tijdschr Geneeskd. 2013; 157(24): A 6025.

  40. Stabilisation of PAS use is priority though the treatment should be integrative and complex including pharmacotherapy starting with less adictive medications like atomoxetin or bupropion and if these are not affective start using stimulants.

  44. Earlybeginningoftreatmentof ADHD delaysthe start of drug abuse. But thetreatmentshould not bewasinterruptedprematurely in adolescence (1).An extensive meta-analysishasclearlyshownthatiftreatmentwithstimulants begun in childhood is lesspossibilityof 27% ofstimulantabuse in adulthood (Wilensetal 2003). Ifthetreatment is startedonly in adolescence, thepossibilityof SUD is increased to 44% (Collins etal. 2008). It wasalsoshownthatabuseofstimulants in connectionwiththedevelopmentofantisocialpersonalitydisorder. • Bejerot S, Ryden EM, Arlinde CM. Two-year outcome of treatment with central stimulant medication in adult attention-deficit/hyperactivity disorder: a prospective study. J Clin Psychiatry. 2010 Dec; 71(12): 1590-7.

  45. There is a constant concern about the abuse and misuse of the stimulant prescribed to treat ADHD. The vast majority of patients use medicament for the treatment of ADHD properly. But a significant proportion reports pressures to approve or sold medicines that have been prescribed to them (1,2). • McCabe SE, Knight JR, Teter CJ, Wechser H. Non-medical use of perscription stimulants among US college students: prevalence and correlates from a national survey. Addiction. 2005; 99(1): 96-106. • Teter CJ.

Pharmacotherapy. 2006; 26(10): 1501-1510.

  46. Around 5% of students abuse stimulants for help with the study. More for improve cognitive functions than to achieve euphoria (1).The effect of 20 mg MPH on long-term memory and understanding of the information did not differ from placebo effect. Amphetamine does not affect short-term memory, long term memory improves, but only when new knowledge already is there. The reason that some students abuse them is to increase in the concentration (58 %), attention (43 %) and feel euphoria (43 %). • Wilens TE, Adler LA, Adamson J, et. al.
